Strange Shapes in the Dark

I woke up one morning, sleeping the the guest bedroom and Liz and Sarah's.  There were these strange dark shaped in the early light before dawn.  I knew what they were but they seemed so strange to me.  So I got out of bed, got my camera and got back in bed and took this photograph.  What you are seeing is my towel, hung on one post of the four-poster bed. In the middle of the photograph, bottom is a "cat tree" I think they are called.  There is a central stalk and then three sort of "baskets" with soft material in them where cats can sleep.  You see one completely and then the other has some stuff in it.  I just thought that this was such a different picture because of the strange shapes.
